Dear God, I hated that Joker Origin confidential arc. It wasn't just the childishly implausible language used in the oh-so-convenient meeting between pre-Joker and pre-Harley; it wasn't the horrible art that displaces character's eyes so that they seem to be made of melting wax; no, it was the core idea that the Joker would be motivated not by personal tragedy and misfortune associated with crippling class differences, ala Alan Moore, but by...a rabbit. In the moon.
The sooner it is forgotten, the better. The Confidential title is a terrible drain on DC's finances, and it lacks the 'loveable fuckup' charm of books such as Superman/Batman. Cancel it already.
